IVI ETHOD OF SECURING WIRE OR THE LIKE IN WOODEN BODIES.

SPECIFICATION forming part of Letters Patent No. 412,691, dated October 8, 1889.

Application filed April 20, 1889.

- depth and length and then forcing the wire sidewise into the incision in such manner that the fibers which form the walls of the slit are momentarily displaced to permit the passage of the wire, and then permitted to react and close over or against the wire and confine the same in place. I prefer for most purposes to produce theincision transversely of the grain of the wood, and by a single stroke of a knife or chisel, so that no portion of the wood is removed, and, although it is not necessary, I recommend that the incision be carried to a depth somewhat greater than that at which the wire is to be buried. In some cases the slit or incision may be produced by a fine saw; but in every instance it should be of a transverse width materially.

less than the thickness of the wire or strip, in order that there may be a considerable displacement and reaction of the fiber, and, consequently, rigid confinement of the wire. For most purposes I prefer to employ a wire of round form in crosssectiou; but it is to be understood that it may be of triangular, square, or other suitable form. When wood of suitable character is employed, and the operation properly performed the walls of the slit or incision will close together so as to conceal and practically cover the wire. The result is a practically solid block with the wire embedded, concealed, and firmly held therein. I prefer that the incision shall terminate short of the edges of the block, so that the ends of the wire shall be concealed and the wire prevented from moving endwise out of position. It is also advantageous in that it leaves the edges of the block un- Serial No. 308,004. (No model.)

broken, so that they are not liable to chip or crack.

My invention is applicable in the manufacture of brushes for securing the wires which hold the tufts, and also for securing wires or like devices to stiifen the body and prevent it from warping, and it is also applicable generally wherever it is required to speedily and firmly embed or conceal wires or rods within a wooden block or body of any kind.

It is to be understood that the incisions may be formed and the wires may be driven to their places therein by means of any suitable character.

Where it is required to close the fiber speedily above the wire, I recommend the damping of the wood; but in most cases this is unnecessary.

In theaccompanying drawings, Figure 1 is a block incised on my plan, one end being also shown with holes therein, as in the case of a brush-body. Fig. 2 is a section on the line a: a: of Fig. 1, illustrating the character of the incisions and the manner of forming the same. Fig. 3 is a similar section showing the wires in position and also the manner of introducing the same. Fig. 4 is a trans verse section of the line y 1].

Referring to the drawings, A represents the block or body; a, the slits or incisions formed therein from its face inward. These may terminate at a distance from the edge of the block, as shown on the left hand in Fig. 1,

or they may be continued to and through the edges, as shown at the right hand in the same figure.

B is a blade or chisel by means of which the incisions may be formed.

0 C are the wires or strips.

D is a tool or blade by means of which the wires may be driven laterally into the slits.

E E are holes, such as used for the reception of the tufts in a brush -body. In the case of a brush-body the incisions intersect these tuft-holes, so that the wires will pass transversely through the holes, as shown in Fig. 4:.

I do not claim herein the means for forming the slits or inserting the wires therein. Neither do I claim herein the block having the holes and the incisions, as this will constitute the subject-matter of a claim in another application of even date herewith.

Having thus described my invention, what I claim is 1. The herein-described method of seating and securing a wire or the like in wood, consisting in first providing the wood with a fine slit or incision, then forcibly inserting the wire laterally into the slit, thereby displacing or separating the walls of the slit, and finally permitting the wood to react to close above the wire.

2. The method of inserting or securing a wire or similar strip in wood, consisting in providing the wood with a fine slit or incision terminating short of its edges, and thereafter 2o forcing the wire, of greater width than the slit,

laterally into the same and below the surface of the Wood, and finally permitting the fiber to react and close together above the wire, whereby the wire is concealed within the wood and secured both against lateral and longitudinal motion.

3. The method of inserting and securing wires orlike metal stripsin wood, consistingin providing the wood with a thin slit or incision and forcing the wire laterally into said slitbelow the surface of the Wood, and finally wetting the wood to cause the reaction of the fiber above the wire.

In testimony whereof I hereunto set my hand, this 8th day of April, 1889, in the presence of two attesting witnesses.
